FABRIC.

SPECIFICATION forming part of Letters Patent No. 368,229, dated August16, 1887.

Serial No. 231,142. (Specimens) T0 aZZ whom it may concern:

Beit known that we, GEORGE O. MOORE and JosEPH W. GREEN, J r., citizensof the United States, residing at East Hampton, in the county ofHampshire and Stateof Massachusetts, have invented certain new anduseful Improvenicnts in Elastic Fabrics, of which the following is aspecification, reference being had therein to the accompanying drawing.

Our invention relates to that class of elastic fabrics in which the faceand back warps are so interwoven with the wefts that no binderwarps arerequired, the object of our invention being to produce a fabric of theclass referred to which will have a clear, deep, and handsome twill, andwhich may also have a black or other colored face and an unmixed whiteback.

Our improved twilled web is made in a double-shuttle 100111, the warpsbeing so disposed as to form a shed through which the shuttles, oneabove the other, will pass simultaneously in opposite directions, oneshuttle above and the other below the rubber warps. Nine harnesses arerequired for the warps, four for the face warps, four for the backwarps, and one for the rubber warps, there being thus eight fibrouswarps and a rubber warp in each dent of the reed. One of the back warpsof each series is carried above (or on the face side) of the face or topweft at each pick, and one of the face warps of each series is carriedbelow (or to the back of) the back or lower weft at'eaeh pick, the orderof change of these wefts preferably being such that each face warp willbe up for three picks and down one pick, and each back warp down threepicks and up one. This disposition of the fibrous threads of the fabricwill balance the said threads evenly on both sides of the rubber warpsin the center of the fabric, so that the latter will be flat and smooth,without the tendency to curl which some similar fabrics have, and thetwill, being unbroken by binder-warps, will be deep and fine. Moreover,the face and back of the fabric will be strongly interwoven and therubber warps will be bound in, while the white back warps will beeffectively covered by the black face warps and the wefts, which latterare also black, so

that the white will not show through on the face of the fabric betweenthe twills, and the back of the fabric will present a clear whiteappearance.

The accompanying drawing is a diagrammatic view representing alongitudinalsection of our fabric, and showing the number ofwarp-threads in one dent of the reed.

In the drawing, a denotes the face warps; Z), the back warps, (indicatedby dotted lines;) a rubber warp; d, the face or top weft, and e the backweft, the said -wefts being indicated by dots. The face warps are eachshown as being up for three picks and down one,and the back warps downfor three picks and up one, the face warps when down passing below thelower or back weft, and the back warps when up passing above the faceweft. In producing this fabric the face harnesses are three up and onedown, and the back harnesses three down and one up. The rubber is.stationary, the top shuttle going through the shed above the rubber andthe bottom shuttle going through the shed below the rubber.

From the foregoing it will be clear that our fabric, which contains anequal number of face and back warps, is equally balanced on both sidesof the rubber, three-fourths of the yarn of the face warps being on theface side of the rubber and one-fourth thereof on the back, andone-fourth of the yarn of the back warps being on the face side of thefabric and three-fourths thereof on the back, thus having with agiven-sized yarn the same weight of material in the face and back of thefabric. From this it results that a smooth and flat fabric, having notendency to curl, will be pro d need.

It will be apparent that the face and back of the fabric will bestrongly interwoven with out the use of binder-warps.

lVe are aware of the fabric covered by the Jefferson Patent No. 216,328.In the production of the said fabric, however, eleven harnesses arerequired, (two for the binde-r-warps,) while ours requires but nine, andthe Jefferson fabric is not equally balanced on both sides, in thatone-fourth of the stock of the face warps and all of the stock of theback warps is on thebaek of the rubber. Moreover, the twill of theJefferson fabric being marred or partly filled up by the binders is notdeep and clear, as is the twill of our fabric, the atthe back of theback weft at each pick, and
